使用HttpClient上传视频文件

我正在构建Java客户端，它将自动将文件从Java服务器上传到Panda实例，该实例使用AMI安装在我的EC2云上。我试图使用Apache HTTP Components上传到熊猫服务器（Panda Stream）。它适用于我的浏览器客户端，但由于某种原因，我无法从该库中上传。这里是我的代码：使用HttpClient上传视频文件

String videoUploadUrl = "http://[panda server ip]/videos/" + getVideoID() + "/upload.xml"; 
File file = new File("/temp/videofile.mp4"); 

DefaultHttpClient httpclient = new DefaultHttpClient(); 
httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); 

HttpPost httppost = new HttpPost(videoUploadUrl); 

MultipartEntity mpEntity = new MultipartEntity(); 

ContentBody fBody = new FileBody(file); 

mpEntity.addPart("userfile", fBody); 

httppost.setEntity(mpEntity); 


System.out.println("executing request " + httppost.getRequestLine()); 
HttpResponse response2 = httpclient.execute(httppost); // <-- FAILS HERE 
System.out.println("finish executing request"); 

HttpEntity resEntity = response2.getEntity(); 

System.out.println(response2.getStatusLine()); 
if (resEntity != null) { 
    System.out.println(EntityUtils.toString(resEntity)); 
} 
if (resEntity != null) { 
    resEntity.consumeContent(); 
} 

httpclient.getConnectionManager().shutdown();

这里是我的错误日志。

我错过了什么？为什么我要弄坏管子。如果我使用相同的代码上传到某个servlet，那么我工作正常，但不会与熊猫实例。有什么想法？

你可以运行一个Wireshark的跟踪，看看是否有在HTTP通信的任何差别 - 此外，没有的事文件的大小？如果它在小文件上失败，跟踪一个小文件可能是有益的 – 2010-10-11 23:05:34
